T-bet, pSTAT1 and pSTAT3 expression in peripheral blood mononuclear cells during pregnancy correlates with post-partum activation of multiple sclerosis
In pregnant women affected by multiple sclerosis (MS) we observed increased percentages of CD4(+)CD25(+)Foxp3(+) T regulatory cells at the 1st and the 2nd trimester of gestation that was associated with a decreased T-bet expression in CD4(+) T cells. In women showing clinical relapse and/or new lesi...

| Résumé: | In pregnant women affected by multiple sclerosis (MS) we observed increased percentages of CD4(+)CD25(+)Foxp3(+) T regulatory cells at the 1st and the 2nd trimester of gestation that was associated with a decreased T-bet expression in CD4(+) T cells. In women showing clinical relapse and/or new lesions at MRI after delivery we found, a higher expression of T-bet, pSTAT1 and pSTAT3 in CD4(+), CD8(+) T cells and CD14(+) cells, associated with an increase of IFNgamma and IL17 production by PBMC at the 3rd trimester of gestation and after delivery. Our data suggest that the expansion of circulating CD4(+)CD25(+)Foxp3(+) regulatory T cells and the lower expression of T-bet in CD4(+) T cells may account for the decreased MS activity during pregnancy. The expression of T-bet, pSTAT1 and pSTAT3 in peripheral blood CD4(+) and CD8(+) T cells and monocytes could be useful to identify MS patients who will develop a relapse after delivery |
